Frostwort + Valproic Acid

Valproic Acid brand names: Depakene, Depacon, Valproate.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Frostwort and Valproic Acid in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the label for Valproic Acid states a food rule worth keeping to.

Frostwort and Valproic Acid

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Valproic Acid and Frostwort in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Frostwort at all — not against Valproic Acid, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

What Valproic Acid’s Own FDA Label Lists

This is not an interaction — none of it involves Frostwort. These are the most notable effects listed in the ADVERSE REACTIONS section of Valproic Acid’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 10 of them are worth acting on rather than waiting out — marked below.

  • Mania or an unusually elevated mood Worth acting on
  • Hearing loss Worth acting on
  • Bone thinning Worth acting on
  • Pain or burning when passing urine Worth acting on
  • Memory problems Worth acting on
  • Low sodium Worth acting on
  • Unsteadiness Worth acting on
  • A slow heartbeat Worth acting on
  • Seizures Worth acting on mentioned in 6.1% of FDA reports for Valproic Acid
  • Hallucinations Worth acting on

Showing the 10 most notable of 72 label-listed effects — ranked by how unusual each one is across medicines generally, with serious effects weighted up.

From the ADVERSE REACTIONS section of the FDA label for Valproic Acid. Read the label on DailyMed › Where a percentage is shown, it is the share of 30,892 voluntary FDA FAERS reports for Valproic Acid that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Frostwort’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Frostwort side to compare — that is a limit of the record, not a statement that Frostwort has no side effects.

How to take them

Some Valproic Acid Products Have a Food Rule — Frostwort Should Not Break It

At least one FDA label for a product containing Valproic Acid says to take it with food. If you take Frostwort on an empty stomach out of habit, keep them separate — and take Valproic Acid with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Valproic Acid products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

irritation may benefit from administration of the drug with food or by slowly building up the dose from an initial low level.

From the Dosage and Administration section of the FDA label we read for Valproic Acid — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

Where does our data come from?
  • Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions. Frostwort is not yet covered by that licensed database, so its write-up cites publicly available medical sources directly (see the references below).
  • Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Frostwort reference on this page ↓
  • Freshness: we automatically re-check this combination every week — this pair was last verified September 20, 2026. The Frostwort and Valproic Acid records this page draws on were last updated June 22, 2026.
  • What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.

About Frostwort

What is Frostwort?

  • Sore throat and mouth irritation
  • Diarrhea
  • Skin conditions and ulcers (topical)
  • Scrofula (historical/traditional use)
  • General astringent tonic

Frostwort is a North American wildflower used in traditional and folk herbal medicine, mainly as an astringent for sore throats, diarrhea, and skin problems. There is very little modern scientific research to confirm that it works or to define a safe dose, so it should be used cautiously and only after talking with a healthcare professional.

Helianthemum canadense · Cistaceae · Whole plant (leaves and aerial parts) · Dried herb, tea (infusion), tincture, sometimes topical preparations

An interaction check asks whether these two react with each other — it does not ask whether Frostwort is a good idea for someone in your situation. Here is what our Frostwort record says about it on its own.

Frostwort: dosing

There is no established or standardized dose for frostwort. Traditional use varied widely and was not based on measured, tested amounts.If you choose to use a frostwort product, follow the directions on the product label and do not exceed them.
